I think on some level this is a rant about Americans, even if you didn't intend it to be one. My Indian and German friends are aware of the fact that not every country has states, even though their countries do. I would bet money on the same being true for Brazilians and Australians. I would bet money on Japanese people being aware of the fact that not every country is partitioned into prefectures.

Maybe this is because Indians, Germans etc. are not socialized to see their way of running a nation as the only way, at least not in the way Americans are. Maybe not. In any case it's a nice demonstration of how collective cultural ignorance leads to annoyed visitors and, one might presume, lost sales.
